Extraction - Problem With Syrian Rue

[develex]

Hi Everyone

SWIM has had some problems extracting the crystals of Syrian Rue!
SWIM doesn't really know if the plan is the right one but It's called with the Persian name of that plant "Esfand"
It has yellowish seeds which contains small black seeds ! What SWIM is doing is this :


1- SWIM smashes them in a plastic bag with a hammer
2- Then add One or Two Drinking Glass of Water + a little Apple Vinegar
3- Boil it for 30-40 minutes for two times
4- throw away seeds and other solid things and just keep the liquid part
5- Add Water+Salt(Half of Drinking Glass full of Salt)
6- Add a few Ice

But SWIM doesn't see any crystals or anything ! Can anyone help SWIM !?
